APPARATUS FOR COILING METAL RODS.

SPECIFICATION forming part of Letters Patent No. 444,652, dated January 13, 1891.

Application filed September 3, 1890- Serial No- 363,871L (No model.)

To all whont it Weary concern.

Be it known that I, HENRY ROBERTS, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Apparatus for Coiling Metal Rods, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a vertical longitudinal section of apparatus embodying my invention. Fig. 2 is an enlarged side elevation of the coiling apparatus. Fig. 3 is a vertical section on the hue III III of Fig. 2. Figs. 4 and 5 are horizontal sections on the lines IV IV andV V of Fig. 2, respectively.

Like symbols of reference indicate like parts in each.

My invention relates to an improvement on the apparatus for coiling metal rods described and claimed in a patent, No. 426,067, granted to me on April 22, 1890, in which is claimed a rotary receiving and coiling cone having a channel which receives the metal at its apex or smaller end and delivers it at its base and mechanism for rotating the cone. The apparatus herein described embodies the invention claimed in that patent, but is an improvement thereon.

The device shown in the patent comprises a coiler consisting of two concentrically-arranged conical shells connected by an intervening spiral or inclined rib.

Y In my present apparatus I do not use the outer cone, or at least I make it only rudimentary in size, and I shape the rib on the inner cone in such manner that it shall serve the function of the outer cone in confining and controlling the rod. The advantage of this improved construction is that I obtain a lighter coiling apparatus and one in which the coiling-channel is easily accessible.

Referring now to the drawings, 2 represents the final set or pair of rolls of the rod-rolling mill, and 3 is the rod which passes through the rolls in the direction of the arrow 1). The coiler B comprises a rotary cone 4, provided at its upper end with a hollow collar 5, which may be conical in form and may encircle the upper part of the cone, as shown in the drawin gs, though this is not essential, since it may the cone.

be above the level of the cone. 111 some respects it is an advantage that the collar should extend around the upper part of the cone, since it thus serves not only as means for re ceiving the rod, as hereinafter described, but it also guides it partially down the surface of The collar and cone are connected by a rib or ribs 6, preferably two or more in number, which extend downwardly from the apex of the cone in spiral lines and are provided with lateral flanges 7, projecting in the direction in which the cone rotates. These ribs may be cast integrally with the cone and the collar, as shown in Fig. 5. The cone is rotary on its vertical axis, the collar being journaled in bearings 8 in a frame or housing 9, and provided with encircling gear-teeth 10 in gear with a pinion 11, which may be driven by a belt-pulley 12 or otherwise. The open upper end of the collar 5 is situate at the extremity of a guide trough or tube 13, which leads from the rolls.

The operation is as follows: The rod as it comes from the rolls passes through the guide trough or tube and enters the open upper end of the collar 5, and thence passes down along the outer surface of the cone 4, where it is engaged by one of the ribs 6. collar rotate in the direction of the arrow 0, and as the rod is fed from the rolls the rib will distribute it in a regular coil upon the receiving-surface or around the usual drum below the cone, and the flange on the rib will prevent the rod from escaping from the cone and tangling. The advantage of using two ribs on the cone is that the rod is engaged more quickly than if one only were used; but, if desired, there may be but one rib and the rib may extend in a straight line, instead of a spiral line.

The advantages of my invention will be appreciated by those skilled in the art.

The apparatus is simple in construction, is durable, and is very efficient in performing the work for which it is intended.

In this specification I do not use the word cone in its strict mathematical sense, but use it generically, meaning thereby a tapering body, whether it be truly conical or not.

I claim- 1. Inmetal-coiling apparatus, a rotary coil The cone and ling-cone having a longitudinal rib with a lateral flange, substantially as and for the purposes described.

2. In metal-coiling apparatus, a rotary coiling-oone having two longitudinal ribs with lateral flanges, substantially as and for the purposes described.

3. In metal-coilin g apparatus, a rotary coiling-oone having an exposed outer surface along which the rod travels, a hollow collar, 10 and driving-gear, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 29th day of August, A. D. 1890.
